LATH-BOLTER.

SPECIFICATION forming part of Letters Patent No. 477,956, dated June 28, 1892. Application filed February 8, 1892. Serial No. 420,162. (No model.)

To all whom it may concern:

Be it known that I, JOHN HENRY PETER- SON, of Portland,in the county of Multnomah and State of Oregon, have invented a new and Improved Lath-Bolter, of which the following is a full, clear, and exact description.

The invention relates to wood-working machines; and its object is to provide a new and improved lath-bolter, which is simple and durable in construction and very effective in operation.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure-1 is a side elevation of the improvement. Fig. 2 is an end elevation of the same. Fig. 3 is a plan view of the same with parts broken out, and Fig. 4 is a rear elevation of the improvement. Fig. 5 is a broken sectional View of one of the top feed-roll shafts and its bearings. Figs. 6 and 7 are transverse sections on lines 6 6 and 7 7, respectively, of Fig. 5.

The improved lath-bolter is mounted on a suitably-constructed frame A, on which is journaled the arbor B, carrying the usual saws O and provided with a pulley D, connected with suitable machinery for imparting a rotary motion to the arbor, and consequently to the saws C. In front of the latter are arranged the bottom feed-rolls E and E, formed with corrugations extending transversely, as is plainly shown in Figs. 1 and 3. The outermost bottom feed-roll E is secured on a shaft F, connected by a train of gear-wheels F, F and F with the shaft F of the other bottom feed-roll E, so that when the shaft F is rotated both feed-rolls E and E rotate in unison.

On the shaft F is secured a bevel gear-wheel G, in mesh with a bevel-pinion G, fastened on the upper end of the Vertically-extending shaft G mounted at its upper end to turn in suitable bearings on the frame A. The lower end of the shaft Gr carries a friction-disk G in frictional contact with the friction-wheel G mounted to slide on and to turn with a driving-shaft G connected with suit-able machinery to impart a rotary motion to the said shaft. The friction-wheel G is held adjustably on the shaft Or, so that the contacting surface of the friction-wheel can be moved nearer to or farther from the center of the friction-disk G3 to increaseordiminish the speed of the shaft G It is understood that the rotary motion of the shaftG is transmitted by the friction-wheel G? to the disk G so that the shaftG? is rotated, and the motion of the latter is transmitted by the pinion G to the bevel gear-wheel G, held on the shaft F.

Next to the bevel gear-wheel G is secured on the shaft F a sprocket-wheel 11, over which passes a sprocket-chain H, extending longitudinally and passing over a sprocket-wheel H secured on the shaft H carrying the spreader-roll I, located in rear of the saws O.

tion and operates in conjunction with the saws O in the usual manner. In the rear of the spreader-roll I is journaled a loose roller J, for guiding the lath over the frame A.

@Above the front bottom feed-rolls E and E are arranged top feed-rolls K, and over the spreaderIand roller J are arranged the similar top feed-rolls K, the two sets being arranged on arbors N and N, respectively, journaled in bearings held in frames L and L, respectively, pivoted at L on top of the main frame A. The frames L and L are arched or curved, as is plainly shown in Figs. 1 and 4, cross each other directly above the arbor B, as shown, and work independently one of the other, allowing allthickness of lumber to be put through machine.

The arbors N and N are each journaled near the top feed-rolls K and K, respectively, in eccentric boxes N while the other box N for each shaft is a ball-and-socket box. A lever N is connected with each eccentric box N and serves to turn the latter'to adjust the respective top feed-roll. In Fig. 5 the cam is adjusted to raise that end of the shaft N.

On the shafts N and N are secured the gear-wheels O and 0, respectively, in mesh 'with the gear-wheels P and P, respectively,

the shafts of which are held on arms Q and Q, respectively, pivoted on the shafts N and N, respectively. The gear-wheels P and P mesh in the gear-wheels Band B, respect ively, the shafts of which are hung on arms S and S, respectively, pivoted on the shafts of the gear-wheels P and P, respectively. The gear-wheels R and R mesh into pinions T and T, respectively, secured on the shafts F and H and the shafts of the said gearwheels R and R are also pivotal] y connected by arms or links U and U, respectively, with the said shafts F and H It will be seen that the rotary motion imparted to the shaft F is transmitted by the pinion T to the gear-wheel R and fromthe latter to the gear-wheel P, which latter rotates the large gear-wheel O, fastened on the shaft N, carrying the top feed-rolls K, so that the latter are set in motion at the time the bottom feed-rolls E and E revolve. As the shaft F rotates the shaft H by the sprocketwheels H and H and the sprocket-chain H,; the rotary motion of the said shaft H is transmitted by the train of gear-Wheels T, R, P, and O to the shaft N, carrying the rear top feed-rolls K, so that the latter rotate'in unison with the spreader-roll I, as well as with the bottom feed-rolls E and E and top feedrolls K.

It will be seen that by swinging the frames L and L farther up or down to raise or lower the top feed-rolls, as desired, the said, top

Y feed-rolls are still rotated from the respective shafts F and 1-1 as the train of gear-wheels held in the respective arms and links permit the up-and-down swinging motion of the arms without the gear-wheels being thrown out of mesh.

It is understood that by having live top rolls, two live bottom feed-rolls in front of the saws, and one live spreader-roll behind the saws the latter are prevented from throwing back cants after they have passed through the saws.

By employing the eccentric boxes N lead can be given to the top feed-roll, so as to hold square-edged lumber up hard against guide.

Having thus described my invention, I claim as new and desire to secure by Letters Patentv 1. A lath-bolter consisting in the frame A, the saw-arbor B, carrying saws, the parallel lower feed-rolls E E in front of the saws and having gearing F F F connecting them, the roller-shaft F, also having a sprocketwheel H, a gear-wheel G, and a pinion T, the spreader I, having a shaft H provided with a sprocket-wheel H and a pinion T, the chain H, connecting said sprockets, the tWo vertically-swinging frames L L, pivoted at L to the upper side of the frame and carrying the shafts N N, provided with the upper feedrolls K K over feed-rolls E E and spreader I, respectively, gear-wheels O O on the rear ends of shafts N N, arms or links U U, S S, and Q Q, and gearing R R P P, connecting the pinions T T, respectively, with the gearwheels 0 0, respectively, and means for adjusting the shafts Nv N in their respective frames, substantially as set forth.

2. A lath-bolter provided with a top feedroll, an eccentric box, and a ball-andsoteket box for the respective ends of the shaft of the said top feed-roll, substantially as shown and described.

3. In a lath-bolter,the combination,with an arched pivoted frame provided with an ec-' centric box and a ball-and-socket box, of a shaft journaled in the said boxes and a top feed-roll held on the said shaft, substantially as shown and described.
